CARDS ADAPTED FOB STATISTICS R SIMILAR- PUR-POSES AND APPARATUS FOR SORTING THE CARDS.

Application filed July 16, 1919, Serial No. 311,389, and in Sweden August 19, 1918.

plication No. 298,561) whereby the cards by being rotatedor moved along curveshaped paths as, for instance, around a pivot needle, are brought into different positions on one or more'sorting needles or the like threaded into the cards at points having the same positions on the same, a relative movement between the cards and the said needles being thereby effected. The invention also relates to a modification ofthe sorting apparatus stated in the said Letters Patent No. 1,334,957 (patent application No. 298,561) corresponding to modifications of the cards.

The principle of the invention is as follows.

In accordance with the said Letters Patent one or more sections are provided on the cards for each ground of classification, for instance age, confession of faith, civil status and so on. In each of the said'sections there are starting points for slots, which points have the same position in all cards. From the said starting points, according to this invention, slots extend in different directions of curve-shaped slots of different lengths and, it may be, also of different directions in such manner, that the mutual position of the terminal points of the slots corresponding to a certain classification is the same on all cards. If the slots extending between the starting points and terminal points consist of curves of suitable curvature, it is evident, that 1. A sorting needle or the like may be threaded into the collection of cards through each starting pointof slots belonging together; v p

2. The cards may be brought to occupy changed positions on the said needle;

3. The cards, as the needle has reached the terminal points of the slots, occupy different positions with relation to one another, according to the different lengths and directions of the slots. i a i The starting point and the terminal point of one of the sections, belonging together, may coincide. In such case the moving of the cards consists of a rotary motion around the said point. Q y

If slots starting from one point only are used, in which one sorting needle or the like is placed, a positive sorting of the cards can not be effected exclusively by these means. For that reason preferably cooperating slots starting from two different points at least are used. However two starting points of the slots may be located in the im mediate vicinity of one another, so that two sorting needles, located close by one another, may be put into the slots. If in such case the slots are so arranged, that two sorting needles or the like may be movedtoward or from one another, a positive movement of the cards into positions determined by the different arrangements of the terminal points of the slots may evidently be effected for reasons stated above.

A plurality of different types of slots arranged in accordance with the general principle stated above may easily be suggested. In the following specification one of the cooperating slots is characterized by the fact, that the starting point and terminal point coincide, so that, as stated above, the cards are rotated around the said point as the sorting needles are moved along the other slots. For the Withdrawing of the cards by groups from the collection, the cards are provided with one or more holes or the like, into which needles or the like are inserted.

Figs. 1 and '2 of the accompanying drawings show as examples two cards of the type stated above. Fig. 1" shows a card of the same collection as the card shown in Fig. 1 but having the slots cut in the sections of the same located differently. Figs. 3 and 4: show modifications of the slots shown in Figs. 1 and 2 respectively. Fig. 5 shows in a vertical section an apparatus for sorting the cards of the type shown in Figs. 1 and 2. Fig. 6 is a section taken in the plane of the line VI-VI of Fig. 5, Fig. 7 shows in a side view a portion of an apparatus for sorting cards of the type shown in Figs. and 4;, and Fig. 8 shows sticks used in the apparatus last mentioned.

Thecards, shown in Figs. 1 and 2, are provided with four circular, sections, which are adapted for different grounds ofclassi- ,fications and in which the slots are effected.

The said sectionsare designated by 1, 2, 3 and 4: and may be adapted for civil status, confession of faith, business, etc., as grounds or classification; As a guidance in producioo v t e sle s hown in Fig. 1? of the collection t e squares ing the slots the sections are divided into Fig. 1 each section has two squares a and b, which portions always are perforated- Besides the slots a hole 0 is provided at the center of the circular sections. In the said squares a, 7) and the hole 0 needles or the like are located for the sorting of the cards inaccordance with a certain classification. In Fig. 1 the section 1 no perforation. In section 2 squares 1 to 9 inclusive are perforated besides the squares a and The squares o and Z2 serve starting points oi; V In the section of another card 0 to .{l nclnsive and 6 to 9 inclnsive are perforated while section 3 of the same card the squares .0. to 2 and to 9 inclusive and in sect on a; the squares Q to 6 lllCluSlYB and 8 and 9 are per forated Ineach case also the squares a and b are peril" 'ated. that the total length of all slots constant Also in this case section 1 has no perforation.

* now two needles or the like are threaded into the squares a; Z- and a pi rot needle into the hole c and the two sqlft ng needles first mentioned are moved toward one another the cards are turned around the pivot needle located in the hole .0, in consequence whereof the corners of cards provided with slots having thesan'ie posit on. will hafire the same position, while the corners of cards provided with slots of aditlerent POSltion occup; another position. The corners of the cards are provided with holes 10, loops or like. Needles or the like are then inserted into the said holes of such cards hv the sorting operation have been brought into the sa ne position. After the removing of the needles by means of which the sorting operation has been e iiected the card's belonging to. the same gronp may be withdrawn from the collection.

Inthe section 3 the squares O to 2 and l to 9 inclusive perforated and in the section l the squares 0 to 8 inclusiveare perforated n ad i i n t the S a e a and b as Usually. Owing to the fact that the f rst square at each section is designated by O, the square remaining after the performance of the perforating operation, designates by its figure the group to which the belongs.

The slots of the card shQWn in Fig. 2; are such that the two sorting needles, threaded into: the curve shaped slot of the cards and adapted to turn the cards around the pivot needle mounted in the hole 0, are nioved f m r asm th s h ert ss aperte s 1' thi C he el sereleee et srlei: 4i e i o osite dies and u mem she. -sqilares d and e s ions 1., 3 and v l'y 21. 91

411s I pa ented til so, is th total length of the slots, adapted for the effecting of the sorting operation, is constant. The squares (Z and 6 may be located at some distance from one another or, as shown. close by one another, so that the slots of each section form a single, continnons slot. as shown Fig. 2. The squares of the one half ofv the sections respectively are pro-- vided with figures tro n 0 to 9, which serve as a guidance during the perforating operation. In the section 2 the squares l to 9 inclusive, the squares Z and 6 a d the square located nearest to the sqnare e the left hand e of the same are perforated. In the section 3 the squares l tol9 inclusive, the quare c and e and the n xt fo r'squ r s located at left hand side of the square 6 ar p rf ed .1 th ection 4 th q a e d and eand all squares, located at the left hand side of the square e and besides the sq are 0 are perforated, In this case the re-' 1 aining square having the figure of the 1 heel; value indicates the group of the r st- 11, t which th c rd belens h t group O, 3 and 9 respectively in the illustrated examples.

For effecting the sorting operation needles are inserted into the squares (Z and e and into the hole- 0 and the torn er needles are then moved from one another, during which operation the corners of cards belonging together are brought into the same position, so that needles may be inserted into the holes provided in the corners for the with drawing of the cards froin the collection after the removal of the needles first mentioned.

Instead of parts of circular lines being perforated, as'shown in Figs. 1 and 2, sectors may be stamped out illustrated in Figs. 3 and which show sections 2 corresponding to the sections 2 or F igs. I and 2 respectively. For the sorting of'cards rovid'ed with slots of the types shown in +igs. 3 and t two sticks are used as shown "in Fig. 8, which are connected with one another atone of their longitudinal edges by means of hinges and eitier in opener in clasped condition are inserted into the slots and then are turned toward or from one another respectively.

The apparatus adapted for sorting cards arranged as stated above may be constructed in many" different manner-s. For instance it may consist of a casing; Figs. 5.21mi 6, on the bottom 11 of which the cards are placed edgewise. In the front and-rear sidewalls of the said casin holes 12"and circular slots 13 are provided; into which and the holes nd means i which the d tes are sorted; h see as t -"re s" r needles dn ixgi sor in g- 0, seat esteem "II is slidablv mounts; Wr t-le is th h el rear th d ng the on.

fit,

the casing. The end wall 15 is fixed to the bottom 11 and the end wall 16 is connected to the bottom 11 by hinges 17 and may be fixed to the front and rear walls by means of hooks. After the needles have been inserted, the end wall 16 of the casing is dropped and the bottom ll'together with the end walls 15, 16 is withdrawn by means of a handle 18, so that the cards become tree and may be turned by means of the needles. The arrangement of the sorting apparatus is adapted to the type of the slots. Thus Fig,

7 shows a portion of the front or rear side wall of a casing adapted for cards of the type shown in Figs. 3 and 4t, the said walls being provided with sector shaped openings 19.

Having now described my invention what I claim as new and desire to secure by Letters Patent is:
